20年代，苏联认为国际联盟是凡尔赛分赃条约的直接产物，是世界反革命势力的总司令部，是帝国主义的侵略工具。1927年，斯大林明确宣布苏联不参加国联，因为苏联反对帝国主义，反对压迫殖民地和附属国，不愿意成为帝国主义阴谋的帷幕的组成部分。30年代随着国际形势的变化，苏联对国际联盟的态度也发生转变，从支持德国打破凡尔赛体系转为支持国际联盟维护世界和平。而巴尔都外交方针的内容之一，是争取苏联进入国际联盟，以国联的力量来抑制德国。1933年11月，法国外长向苏联大使提出苏联参加国际联盟的建议。得到苏联同意后，他又做了大量工作，推动国际联盟以绝对多数票赞成接纳苏联并推举它担任理事会常任理事国。1934年9月，苏联正式加入国际联盟。

——摘编自王斯德《世界通史》（第三编）

    Michael Jackson was one of the world's best singers. He was born in the middle west of the city of Gary， Indiana， in 1958. He began singing with his four brothers. They called the group， “The Jackson Five”. The group became very popular after appearing on a television program. In 1970 the group made their  first record with the name of I Want You Back. It was very popular. One of their hit records was Never Say Goodbye.

    Michael was good at dancing as well as singing， for example， his dance moves and moon walking. He was asked to act in a film in 1978 for the first time， and in the same year he made a record on his own， which was sold eight million copies all over the world.

    Michael nearly didn't go out because he was too famous. Once his fans went off in a faint(晕倒）when they saw him at the concert. No one can do it by now. He lived in a large house and kept lots of animals. He never ate meat. He often raised money for charity. This made him win the Guinness world Records（吉尼斯世界纪录）in 2006. He died on June 25th， 2009， but he would live in our hearts forever.
